D-backs acquire Aaron Heilman

PHOENIX — The D-backs bolstered their bullpen Thursday acquiring right-hander Aaron Heilman from the Cubs in exchange for a pair of Minor Leaguers.

Heilman was 4-4 with a 4.11 ERA and one save in 70 games for the Cubs. The 31-year-old walked 34 and fanned 65 while holding opponents to a .257 average.

The D-backs sent left-handed pitcher Scott Main and infielder Ryne White to the Cubs. Maine, who pitched in the Arizona Fall League this year was a sixth-round selection in the 2007 First-Year Player Draft and split time this past season between Double-A Mobile and Triple-A Reno.

White, meanwhile, was a fourth-round pick in the 2008 First-Year Player Draft. Last season he hit .266 with six homers and 52 RBIs for Class A Visalia.

Heilman is 26-37 with 10 saves and a 4.22 ERA in 375 career games with the Mets and Cubs.
